Most of us see going to the grocery store as a mundane chore that has to be done if we want to put dinner on the table.
However, for those of us that are visually-impaired – a trip to the supermarket can be a painstaking ordeal.
Now, engineers at Penn State are working on a system called Third Eye that uses technology to enable visually-impaired individuals at the store.
“You always have to find someone at the store to help you,” Michelle McManus, president of the Happy Valley chapter of the National Federation of the Blind, said in a Penn State press release.
“Then you have to explain exactly what you want,” and rely on someone else to get it for you.
In order to develop their shopping-oriented visual system, the researchers started with what they called a “Wizard of Oz” prototype. The prototype involved a subject wearing a chest-mounted iPad that used the tablet’s camera to send images of items to a nearby control room.
Based on these images, the control room “Wizard” would give verbal instructions to the subject.
